With only 6 jumping passes men can do a layout like
4Lz
4T+3T
4S
4T
3A
3A+2T+2Lo
No wimpy triple Lutzes or half-loop combination
There will be 7 jumping passes in 2018-19, not six. So there probably will need to be a triple lutz in there someplace.
This skating plan assumes a skater can land four quads and two triple axels cleanly, which isn't easy to do. With the increase in deductions for falls, skaters need to be sure they can do at least a two-footed or under-rotated landing on all their jumps. If not, the deductions for the falls are going to pile up pretty quickly.
The other factor is that in 2018-19 is that the GOES will increase to a range of 0 to +/-5. So a badly done quad may end up with a 0 or +1 while a nicely done triple lutz could end up with a +5. That's a much bigger difference than now.
Another reason why the ISU increased the range of the GOEs when they reduced the jumping passes for Men in 2018-19 is to make sure skaters still had a chance of setting points records. If the GOE range had been kept the same with only 7 jumping passes, Hanyu's records would have stood forever. The new range of GOEs gives skaters at least a hope of breaking Hanyu's records.
